The biggest difference between DC brushless motor and brush motor is the difference in the motor control mode. Brush motor speed needs to be achieved with the help of mechanical commutator, while the DC brushless motor is through the electronic commutator to achieve speed control. Because electronic commutators allow for more precise control, brushless DC motors are more widely used in high-performance applications. In addition, because there is no mechanical friction, DC brushless motors operate more efficiently and have a longer life.

1. Structural differences:

Brush motors change the direction of current through the contact between the brushes and the rotor, while DC brushless motors automatically change the direction of the rotor through built-in sensors and external electronic speed regulators. Therefore, the structural differences between DC brushless motors and brushed motors are mainly in the rotor windings, bearings and brushes. Brushless motors do not need brushes, so they can improve rotor speed and life, and are also more reliable.

2. Control system differences:

The control of brush motor usually uses PWM scheme, i.e. the control is achieved by adjusting the switching time of the brushes. The control of DC brushless motors, on the other hand, requires the use of electronic speed controllers and control algorithms to achieve this. The control system of DC brushless motors is complex but more accurate, allowing better control of operating efficiency and performance indicators.

Overall, DC brushless motors have higher efficiency, longer life and more stable performance than brushed motors, so they are widely used in high-end applications. However, at the same time, DC brushless motors also have higher cost and production difficulties, so brushed motors are still used in some low-end applications.

The core of motor production automation lies in the automatic control of the production process and is realized through industrial automation equipment and systems. This includes the use of CAD software for motor design, automated production of components through digital manufacturing technology, and intelligent assembly line assembly, etc. Through large-scale production data analysis and quality control, we achieve stable product quality and improved production efficiency.
